Formal attire refers to a specific type of clothing that is worn for special occasions or events that require a more sophisticated and elegant appearance. This includes outfits such as suits for men, evening gowns for women, and other dressy clothing that is not casual. Formal attire is often required for events like weddings, galas, business meetings, or award ceremonies.
The term "formal attire" combines "formal," which comes from the Latin word "formalis," meaning "pertaining to form," and "attire," which originates from the Old French word "atirier," meaning "to equip" or "to dress." Therefore, "formal attire" literally means clothing that is equipped for formal occasions.
